Interpretive Summary: Brown marmorated stink bug (BMSB), Halyomorpha halys (Stål), is an invasive species that has become a key pest of many agricultural crops. Long-lasting insecticide nets (LLINs), which have insecticide incorporated within the fibers, have been widely used for the control of malaria and other insect-vectored diseases. In this study, we evaluated the toxicity of a deltamethrin-impregnated LLIN (ZeroFly) for control of BMSB. Mortality of BMSB was evaluated in two laboratory experiments. In the first experiment, third and fourth instar nymphs and adults were exposed to the ZeroFly net for various intervals and then mortality was recorded after 24 hours. In the second experiment, adult BMSB were exposed to the ZeroFly net, a lambda-cyhalothrin treated net, a dichlorvos strip, and compared with untreated controls inside of Dead-Inn stink bug collection jars. Exposure to the ZeroFly net for 10 s resulted in >90% mortality of BMSB nymphs and >40% mortality of BMSB adults after 24 hours. Longer exposure to the ZeroFly net resulted in higher mortality. No BMSB adults escaped from jars with LLINs, and mortality from LLINs was better or equal to that of the standard dichlorvos strip. Based on these results, LLINs offer utility as alternatives for managing BMSB or retaining them in traps as part of integrated pest management programs.

Technical Abstract: Long-lasting insecticide nets (LLINs), which have insecticide incorporated within the fibers, have been widely used for the control of malaria and other insect-vectored diseases. Only recently have researchers begun exploring their use for control of agricultural pests. In this study, we evaluated the toxicity of a deltamethrin-impregnated LLIN, ZeroFly (Vestergaard-Frandsen) for control of the brown marmorated stink bug (BMSB), Halyomorpha halys (Stål). In the lab, exposure to the ZeroFly net for 10 s resulted in >90% mortality of H. halys nymphs and >40% mortality of H. halys adults. Longer exposure to the net resulted in higher mortality. In another experiment, a 15-cm2 sheet of ZeroFly net placed inside of the stink bug trap provided long-lasting kill of H. halys adults equal to or better than standard dichlorvos kill strip. Potential for the use of ZeroFly nets for H. halys integrated pest management (IPM) is discussed.
